Extensive nodular cutaneous amyloidosis: an unusual presentation

Amyloidosis is characterized by the deposition of a group of unrelated proteins leading to changes in tissue architecture and function. The nodular variant is the rarest form of the cutaneous amyloidoses. We report a patient with localized nodular amyloidosis without systemic amyloid involvement or paraproteinaemia after 6 years of follow-up. The unusual aspects of our case were a plaque presentation rather than nodular, and the disseminated pattern observed.     

Urodynamic assessment of the bashful bladder

PURPOSE: We prospectively studied the potential contribution of ambulatory urodynamic monitoring in men with urinary symptoms unable to initiate a void on conventional video cystometrography. MATERIALS AND METHODS: A total of 40 consecutive symptomatic men with a median International Prostate Symptom Score of 19 (range 1 to 29) and median age of 51.9 years (range 30 to 75) who were unable to void during video cystometrography underwent ambulatory urodynamic monitoring. Solid-state transducers mounted on silicone coated catheters were inserted urethrally and rectally, and connected to a portable recorder. Subjects voided in private into a specially designed flow meter, which they connected to the recording device. RESULTS: Of the patients 2 (5%) failed to attend ambulatory urodynamic monitoring, despite multiple reminders, and in 1 (2.5%) the trace was uninterpretable. Pressure flow data were available for the remaining 37 patients with mean plus or minus standard deviation 2.72+/-0.1 storage void cycles recorded per patient. All 6 patients (15%) with obstruction were older than 40 years. In 6 cases (15%) obstruction was equivocal and the remainder were unobstructed. Transurethral prostatic resection in 2 and urethrotomy in 1 of 6 patients with obstruction resulted in subjective and objective improvement. CONCLUSIONS: The bashful bladder syndrome was not associated with any specific urodynamic diagnosis. Ambulatory urodynamic monitoring will yield a urodynamic diagnosis in more than 90% of cases after failure to record void data on video cystometrography. A surgically correctable cause of symptoms can be found in about 20% of men older than 40 years. The contribution of ambulatory urodynamic monitoring compared to more conventional evaluation in men younger than 40 years is negligible.     

海南省性罪错妇女11年性病感染情况调查分析

目的 通过对11年来性罪错人员性病感染情况的调查分析,掌握性病在性罪错妇女中流行的特点,为政府部门对性病防治政策的制定提供科学依据。方法 对1990年元月至2000年12月海南省妇女收容教育所被收教的性罪错妇女进行性病检查,统计其各种性病的发病人数,然后进行分析。结果 11年中共收教4780人,其中感染淋病、非淋菌性尿道炎(宫颈炎)、尖锐湿疣、梅毒、生殖器疱疹、HIV共2967例,阳性率为62．07％,其中非淋菌性尿道炎(宫颈炎)1826例(38．20％)、淋病469例(9、81％)、梅毒414例(8．7％)、尖锐湿疣246例(5．14％)、生殖器疱疹11例(0．23％)、HIV阳性1例(0．02%)。结论 性罪错妇女六种性病的患病率很高,达62．07％,其中非淋菌性尿道炎(宫颈炎)为其主要病种,淋病的患病率逐年下降,梅毒的患病率逐年上升,尖锐湿疣基本稳定,其流行特点值得我们重视。     

甲状腺机能亢进症危险因素病例对照研究

目的 探讨各危险因素与甲亢的关系。方法 对三亚地区110例甲亢采用1：2配比的病例对照研究,资料处理采用条件Logistic回归分析.结果 甲亢发病与下列5因素关系密切：家庭年收入(OR=2．055)、食用碘盐(OR=2．133)、喜食海产品(OR=2．183)、感染(OR=2．382)、家庭生活事件(OR=3．017) 结论 家庭生活事件、感染、喜食海产品、食用碘盐、家庭年收入增高等是甲亢的危险因素。     

海南省大劣按蚊实验室自然交配的驯化研究

目的 建立实验室大劣按蚊自然交配繁殖种群,为同类研究提供依据。方法 将野外捕捉并在实验室人工交配繁殖至第61代的大劣按蚊,按不同雌雄比例先后顺序置于大、中、小三种不同型号的蚊笼中喂养、驯化、观察产卵情况并计算产卵数和孵化率。结果 在大、中、小蚊笼内的分别驯化至第15、10和18代时成蚊卵的孵化率各达到82％、83．4％和80．7％,成功建立小蚊笼自然交配的大劣按蚊种群。结论 经实验室驯化的大劣按蚊能够自然交配、产卵、繁殖,有助于建立实验室自然种群。     

A study on motility of sphincter of Oddi in postcholecystectomy syndrome

Endoscop c manometry of sphincter of Oddi(SO)and serumlevels of gastrin,glucagon,and somatostatin were measured in patients withpostcholecystectomy syndrome(n=12),asymptomatic cholecystectomised pa-tients(n=6),and controlled subjects(n=14).Pentagastrin-stimulated gastricacid secretion test was also performed in part of patients who had symptoms orno symptoms after gallbladder resection.The results showed that the patientsof symptomatic group had hypertonic dyskinesia of SO as shown by deep andwide waves superimposed on high basal pressure plateau of SO.The symptoma-tic group also had a higher serum level of gastrin and a greater BAO than tho-se of other two groups.No difference of serum levels of glucagon and soma-tostatin was found among these three groups.The hypertonic dyskinesia of SOand hypergastrinemia are considered as possibly important factors in the patho-genesis of postcholecystectomy syndrome.
